Rice bacterial leaf blight is caused by  Xanthomonas oryzae  pv.  oryzae  ( Xoo ) and produces substantial losses in rice yields. Resistance breeding is an effective method for controlling bacterial leaf blight disease. The mutant line H120 derived from the  japonica  line Lijiangxintuanheigu is resistant to all Chinese  Xoo  races. To identify and map the  Xoo  resistance gene(s) of H120, we examined the association between phenotypic and genotypic variations in two F 2  populations derived from crosses between H120/CO39 and H120/IR24. The segregation ratios of F 2  progeny consisted with the action of a single dominant resistance gene, which we named  Xa46 (t).  Xa46 (t) was mapped between the markers RM26981 and RM26984 within an approximately 65.34-kb region on chromosome 11. The 12 genes predicted within the target region included two candidate genes encoding the serine/threonine-protein kinase Doa (Loc_Os11g37540) and Calmodulin-2/3/5 (Loc_Os11g37550). Differential expression of H120 was analyzed by RNA-seq. Four genes in the  Xa46 (t) target region were differentially expressed after inoculation with  Xoo . Mapping and expression data suggest that Loc_Os11g37540 allele is most likely to be  Xa46 (t). The sequence comparison of  Xa23  allele between H120 and CBB23 indicated that the  Xa46 (t) gene is not identical to  Xa23 .
